Funding:Work supported by Brookhaven Science Associates, LLC under Contract No. DE-SC0012704 with the U.S. Department of Energy.The development of HTTP service interfaces* to the BNL Collider-Accelerator Department (C-AD) controls system opens up the ability to more quickly and easily adapt existing codes developed for other systems for use at RHIC. A simple particle accelerator online model built for commissioning the NSLS II** was adapted for use with the Low Energy RHIC electron Cooling project (LEReC)*** and the Coherent Electron Cooling (CeC)**** proof of principle experiment. For this project, a set of python modules and a python application were adapted for use in RHIC by replacing NSLS II control system interfaces with python modules that interface to the C-AD controls HTTP services. This paper will discuss the new interfaces and the status of commissioning them for operations.* T. D'Ottavio, et al., these proceedings ** S. Seletskiy et al., TUPMA054, IPAC15, 2015. *** A.
